- PROCESS OF PRINTING FABRICS.

K0 Drawing.

To all whom it may concern:

Be it known that I, GEORGE PRmoLD, a citizen of the United States, and aresident of Linwood, county of Delaware, State of Pennsylvania, haveinvented certain Improvements in Processes of Printing Fabrics, of whichthe following is a specification. My invention relates to certainimprovements in the process of printing designs upon woven fabrics, suchas carpets, tapestries, &c.

One object of my invention is to improve the process of printing uponthese materials so that the color design will extend a considerabledepth into the body of the fabric.

A further object of the invention is to use a dye, such as anilin, .orits equivalent, as the coloring matter and to deposit it on the fabricwith a vehicle, then removing the vehicle, leaving the coloring matterin the fabric. i

The fabric after being woven is passed through a printing machine of thetype illustrated in thepatent granted to William H. Waldron on the sixthday of July, 1915, No. 1,145,821.

This machine consists essentially of a frame having. a series ofprinting blocks and means for reciprocating said blocks and a series ofpigment carriers, which are arranged to reciprocate under the severalprinting blocks 50 as to supply the blocks with the coloring matter tobe impressed upon the fabric. The pigment I use in the present instanceis made of anilin colors and is mixed with starch, flour, or equivalent.

material, to give it sufficient body. The fabric is intermittently fedthrough the machine and the impressions are made by the printing blocks,the number of printing blocks depending upon the design and the numberof colors desired. The printed fabric passes from the machine and intoa. steam chamber having rollers at each end carrying bands at each sideto which the fabric is clamped by any suitable clamping device.

The steam in. the chamber causes the anilin colors to pass into thefibers so that the colors that were deposited on the surface of thefabric run and extend into the Specification of Letters ratent. PatentedJan. 29, 191$.

body of the fibers. Afterthe goods as from the steam chamber they arefesto ned in a drying chamber by looping the fibers over in the ordinarymanner of festoon drying.

- suitable bars, which are traversed on rails This drying evaporates themoisture in'the 7 material so that the starch or flour become dry,leaving the anilin colors in the fibers. In

order to remove the starch or flour, or like material, that is used tocarry the anilin dyes, I pass the fabric through a brushing machineconsisting of a series of abutments opposite brushes. There are a numberof these brushes and at intervals there is a series of beatersconsisting of a rotating drum having a series of bars thereon, whichstrike against the back of the fabric. The brushes act against the faceof the fabric, while the abutments support the back "of the fabric.These brushes remove the dry flour orstarch and the action of theheaters is to cause any particles of starch or flour that have ai'nedaccess to the body of the fabricto By the above process, I am enabled toprint elaborate designs and to cause the dye to penetrate the full depthof the fabric so e removed therefrom and when the fabric passes that theentire surface of the fabric has the same appearance as a fabric wherethe strands are dyed prior to being woven.-

More elaborate designs can be made by my improved process than bypresent methods of printing fabrics and the cost of the process ofprinting is considerably reduced.

Although I have described the use of starch and flour as a carrier forthe coloring matter and although I have described anilin colors as used,it will be understood that other vehicles may be used which can beconverted into powder andremoved by colors may also be used Withoutdeparting from the essential features of the inventiom I claim:

1. The process herein described of printing woven fabrics, said processconsisting in mixing a color capable of dyeing a fabric and a vehiclecapable of being dried and dusted out of the fabric printing the fabricwith said color, then su jectin'g the printed fabric to heat andmoisture so as to cause the color material to enter the fabric, thendrying the fabric so as to reduce the "ehicle to a solid, then removingthe vehicle in the form of dust, leaving the coloring in the fabric.

2., The process herein described of printing Woven fabrics, saidprocessconsisting in mixing a color capable of dyeing the fabric and a vehiclecapable of being dried and dusted out of the fabric,print-ing the fabricWith said color, then subjecting the printed fabric to steam so as tocause the oloring matter to enter the body of the fabric, then dryingthe fabric so as to reduce the vehicle to a solid, then brushing out theVehicle in Leashes the form of dust, leaving the color in the fabric. 7

3. The process herein described ofprinting Woven fabrics, said processconsisting in printing a surface of thefabric With the color carried bya vehicle of starchy material, then subjecting the printed fabric to theaction of steam so as to cause the coloring matter to travel into thefiber of the fabric, then drying the fabric so as to solidify thestarch, and finally subjecting the fabric to a beating and brushingaction so as to remove the starchand flour, leaving the coloring matterin the fabric.

4:. The process herein described of printing Woven fabrics, said'process consisting in printing the fabric With a composition consistingof an anilin color and a starchy vehicle, subjecting the fabric to theaction of moisture and heat to cause the anilin colors to penetrate thefabric, then drying the fabric to solidify the vehicle, then removingthe vehicle from the fabric, leaving the anilin color therein, and thensizing the back of the fabric.

In Witness whereof I affix my signature.

GEORGE PRIFOLD.
